I have a 2000 Acura Integra LS. I noticed when driving the car and then come to a full stop, the temperature goes up nearly close to 'H'. But as soon I gas it, temperature goes back to normal. Happens intermittently. Check the coolant level, okay. Check for leaks, none. Could it be my thermostat going bad? Any feedback is greatly appreciated. Thanks.

Might be a t-stat sticking or other restriction. Is the radiator cold?

I have seen waterpump on there way out do similiar as well but fairly rare.

Has there ever been stop leak added?

- Radiator temp is at normal.

- Changed the timing belt and waterpump at 95k.

Has there ever been stop leak added?
- Never.

What is the record on coolant flushes?
- I'm the second owner, bought the car when it had 65K. Changed coolant and thermostat at 78K. Then changed coolant again at 109K, but not thermostat.

Thanks for that info. Thats tales a little cloudyness out. I would try a thermostat if it was mine. The trouble to take it out to test it.(Especially being intermittant) I would just put in a new one. The intermittantcy and the restricted flow thoughts help support this. It's possible of other circulation restrictions, but the t-stat is more common. Or don't do anything and monitor the situation until it is more consistent or does peak into the red on the gauge. Which you don't wnat.
